Elias was in the middle of his set when retro footage from Yankees games began playing on the screens inside of MetLife Stadium -- then Cena's old entrance music hit.

Cena sauntered down the ramp in a Yankees jersey and the Dr's signature chain, then confronted Elias before hitting him with an FU and Five Knuckle Shuffle.
